N.W.T. forest fires to blame for slow fishing season

It's been a slow summer for commercial fishers in the Northwest Territories, who have netted less than half of last year's catch.

The lower numbers are partially due to forest fires, according to Jason Grabowski with the Winnipeg-based Freshwater Fish Marketing Corporation, whichbuys, processes and marketsall freshwater fish caught for commercial sale in Manitoba, Alberta, and the Northwest Territories.

According to a report conducted by the United States Department of Agriculture in September 2012, wildfires can affect the quality of the water as well as the channels in a stream.

"If a severefire burns near or across a stream, water temperature can increase substantially," the report read. "Dissolution of smoke, ash, and volatile compounds can alter pH concentrations of trace metals, nutrients, and other chemical constituents in stream."

The report says that can affect what's growing in the body of water, which is often what fish eat. It also says warmer water temperatures can affect where fish swim, which could be different fromwhere fishermenin the Northwest Territories are looking.

Grabowski says a lateice break-up on the rivers has also affected the season.

"They haven't had their run yet from the Mackenzie,"Grabowski said. "So a lot of guys are waiting around the Mackenzie for the fish to start moving, but they really haven't. Last year, it started the third week of July and that was late."

Grabowski says fishers have netted111,000kilograms of fish so far.Last year, they caught 275,000kilograms.

He says fishermenare considering working into the winter.
